Product Description

Introduced bernard technology electric actuator quarter-turn electric actuatorAS**5, BS**0,A+RS**0

Cut-off signal protection

The actuator stop at the original, all-on or all-off position which is instructed by users as the signal is interrupted by accident or the signal is less than 3mA (called the cut-off signal) in order to guarantee the whole systems safe and stable. It also possesses the output connection point for alarm.

Over-torque of two- way protecting function

When the torque exceeds the setting scope, the torque switches inside the actuator and outputs a signal to the controlling circuit for stopping the motor to protect the valve, the driving parts and the motor. After the mechanical over-torque fault is relieved, shutting down the power supply or an instantaneously reversed signal, the actuator will come back to turn normally.

Auto switch function

The actuator can implement three kinds of switch function Distant- automatic / distant -manual /local. It can also operate electrically and manually on the spot.

The pros and cons of switch function

The control panel program has the pros and cons of switch function that satisfied different situations on-the-spot.

Dynamic braking

The control panel program of modulating model electric actuator has the dynamic braking function that can prevent motors inertia movement and ensure the stability and reliability of the controlling system.

Servo-motor with double protection and high-efficiency

All the motor has the thermal and open-phase protecting function. When there is an unexpected failure, it will shut off the power supply effectively so as to protect the motor. It serves as a good servo characteristic and it will not overheat after frequent movements.

Stronger anti-interference function

With the imported main chip of control panel and stable performance, the actuator has the stronger anti-interference capability. The and output signal adopt the shielded wire.

~Main function

Synopsis:

Uses the world advanced electronic type technology, The bell series product has the many kinds of control mode, Many kinds of protections function.(Has over-torque protection, has broken signal protection, electrical machinery excessively hot protection, over-travel protection, scene operation function and unique cam mechanism, self-locking an

1th, advanced series electronic type electric Actuators

High pointing accuracy integrated product

This product output corner pint pointing ,the overall proportional control the amplifier ,the position transmission function concentrates in together ,Realizes the true integration ,Receives the ***0mA signal ,Outputs the ***0mA signal.

Bidirectional moment of force protection function

Namely when valve in normal work process , Because the accidental reason creates the valve deactivation ,And causes in the situation which the electrical machinery stops up transfers ,This actuator immediately automatic turnoff power source ,Electrical machinery because of power failure but knock off ,Thus the protection main engine equipment is not damaged ,At the same time sends out the breakdown alarm, Prompt operator.

The over travel protection function

When the actuators output effective traveling schedule surpasses the hypothesis traveling schedule ,This function has an effect ,Thus about guaranteed does not surpass.

Break the signal protection function

When signal accident severance the implementing agency stops in the current working position cannot create all opens ,the entire pass phenomenon ,Thus guarantees the overall system the stability ,the security ,the security ,And has for reports to the police with the output contact.

The automatic cut over function

The actuators may realize the distant place to be automatic/Distant place manual/on the spot Three kind of conditions cuts ,Withdraws when the electrically operated operation ,Regardless of the electrical machinery is the rotation perhaps the static condition ,All can safely gather to the hand wheel position of operation.

The electrical machinery electric brake function

In order to over come the system the inertia to walk , On the adjustment electrically operated actuators high efficiency electrical machinery its control circuit has the electric brake function.

High performance servo electrical machinery, And has been hot , breaks protects the function.

High motor to have the good servo characteristical , Frequently moves does not give off heat. The electrical machinery heat, has broken protects the function and the over-torque protection function has been similar ,When electrical machinery because the accident stops up the extension ,When other functions have not all had an effect, This function effective will shut off the electromechanical power supply Thus realizes the dual protection.

The strong anti-jamming ability

Control version main chip uses the import product , The performance is stable ,Enable the actuators to have the strong anti-jamming ability ,The output signal uses the shielded wire.
